l Application inea september 1925. serial No. 54,252.

The present inventionv relates to a mounting for use with a closuremember, such for instance, as a door for closing the opening ofyan ovenof a stove, or for general usey in a similar or `analogous construction.s

The object of the invention is to provide a door or closure mounting inwhich the pivotal mounting or hinges for therdoor are concealed so thatthe appearance of the door whenin closed position shows no appearance ofhinges on the outside thereof.

A further object is to provide 'a mounting in which the pivotal mountingis concealed, and the. door is spring retained so that when moved aboveits horizontal open position the door will be yreturned to its closedposition by the spring action, andwhich mechanism will ermit the doorftobeheld in open position ythe weight. ofthe door.

Reference should be had to the accom panying drawing forming apart ofrthis specification, in which Fig.k l is a front elevation of a stovehaving a door embodying the present invention; Fig. 2 is a side elevation with portions in section showing a part of the door mounting;Fig. 3 is a rear elevationshowing a part of the door mount ing; Fig. 4is aside elevation with portions in section 'showing ythe door mounting;Fig. 5 is a fragmentary view in elevation showing a part of the doorconstruction; Fig. 6 `is an end elevationof the showing inFig. 5; Fig.7y is 'lan elevationwith portions in section showing the portion of thepivoting mechanism which co'-operates with that shownin Figs. 5 and.

In thefdrawings, the doorisindicated by the reference numeral k,1. Thisdoor at the left and right lower corners is provided with a roundedextension 2 from whichv there laterally extends a finger 3,y and therealsoy extendsv a downwardly depending curved inger y4. The lower edge ofthe door is roundedas indicated atl. -In the drawings (3 indicates theyfront of the stove having ay suitable opening for which the door lforms a closure, it beingpunderstood that the ,disclosure with respectto the stove is merely indicative ofone'form which the inventionmavassume. t

The portion of the front vmember 6 ladjacent rthe lower edge of the door`l vis alsoy rounded, as indicated at 7, and the in ner end kof theroundportion 5 is closely positioned with to the lower edgeof the openinginthe member 6 when the door l is in its closed position.k At each sideof the lopening in `the memberk 6 and upon the insidesurface there isformed or otherwise secured a rounded projection 8.. In the case t'egral`with parts of the stove yfront, or

the stove front 6 thejrounded finger 4 will lie against the curvedsurface of the member 8, and when the door is moved to its open andclosedposition the rounded fingerv v4v upon the rounded surface of themeimberS.` ,A Y' s It lwill be understood that the projecting member 8is duplicated upon opposite ksides,

will slide of the opening in the stove front, and likewisethe projectingfingers 3 and 4 are duplicated at `opposite left and right lower cornersof the 'door.` Y To the finger 3 there is attached one end of a spring9, the ,opposite end of the spring being securedto-a portion of the rear'sur'-v The point of 5U of a stove this projection 8 may be cast in- `itmay be separately formed andattached. s y

kface of the stove front, asclearly indicated' Aat l0 in Fig. n e f n le attachment of the spring 9l upon the arm 3 is such that whenthe doorvn is in closed position, as indicated kin full lines in Fig. 4, the pullof the spring is off center with respect to the pivotal mounting of thedoor,` andthereforethe door is held in its closed position` `When thedoor` is moved to open position, as indicated in dotted lines in Fig. 4,the pivotal point ofy the` i `spring 9 uponfthe arm 3 ismoved so that itis substantially in line with the center of the pivot of .the door, andthiscondition added to the fact that the` `weight, of the door initsopen position is overhanging, is sufficient to overcome the retractiveeffort of the-spring 9 so that the door will. remain in openzposition.However, when the door is raised through a part of its movement toclosed position, the action of they springs will become effective andreturnthe. door to its closedfposition. y n

HVAs, before described, the lower edge of the door l is rounded, askindicated kin Fig. 2, and thisconstruction in conjunction with therounded lower edge of the. opening in the stove front 6 as the cover ismoved to its open position.

The action of the co-operating members which forni the pivot for thedoor may be described as a cantilever action.

In order to insure that the curved arms l carried by the door, and themembers 8, shall stayin contact a't alltim'es, it is desirable toprovide guards,`one of which guards is indicated at'll in Figs. 2 landA8. "These guards are for-ined with an inner curved surface l2 whichis acomplement of the-curved surface on theineinber 8. Therefore, the curvedfinger 4 may move upon the curved surface of the member 8 withouthindrance, due to the presence of the guard.V At. the same. time thisguard will preveii'ttlie accidental displacen'ientof-the curved fingersa with respect to the members' 8 with which they cooperate'. @The guardll is secured at its ends upon the inside of thestove front.

Fromk the construction vas it is described, it will `be seenthat'theentire pivotal mounting for the door is behind the stove front, and nopart of it is visible from the outside of thestove front, nor are thereany outwardly extending hinges or parts of 'hinges orpivotal mountingssuch as are customarily employed in connection withstove doors andstructures of similar nature.

Having described my invention, I claim 1..The combination with a memberhaving an opening thereimof a closurev forsaid opening, said closui'ehaving rearwardly extending portions at opposite'sides thereofwith adependingcurved arm, extensionsv carried by the said member adjacent theopening and upon the inside of the said member, having a curved surfacewith which the inner surface of said curved arms on the-l elosureco-operate, and resilient means cooperating with the said closure andtending to return the closure to closed position when the closure isintermediate between open and closed positions.

2. The combination with a member having an opening therein, of 'aclosure for said opening, said closurehaving rearwardly exand tending toreturn the closure to closed position when the closure is intermediatebetween open and closed positions.
